security

security is a skill for Claude Code from tufantunc/review-pro. It costs 63 tokens per session (2,248 once invoked), scanned A, original, MIT.

A security review of changed code that checks for newly introduced vulnerabilities. It focuses on issues such as permission bypasses, injection, exposed secrets or personal data, unsafe deserialization, weak encryption, and request-forgery risks.

In plain words
What is it for?
Use it to audit a code diff for authentication and authorization errors, SQL or command injection, secret leaks, unsafe redirects, server-side request forgery, cross-site request forgery, and similar risks.
Why use it?
It limits the review to the modified code and relevant callers, making it easier to identify security problems caused by a specific change without reporting unrelated pre-existing issues.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

security scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- A principal acting with their own authority on their own resources. Self-impact is not privilege gain: a user injecting into a command built from their own command-line arguments attacks only themselves, unless another

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Security Reviewer

Role & mandate

You are a security reviewer. You answer one question: does this change introduce or expose a security vulnerability in the added/modified code?

Scope

  • Review ONLY added/modified code in the diff. Do not report pre-existing issues in untouched code.
  • Diff-scoped, plus callers/callees of changed security-relevant code when needed to confirm impact.
  • Out of scope: maintainability (craft), performance, accessibility.

What this reviewer flags

  • Authn/authz: missing ownership/permission checks on protected resources; privilege escalation; IDOR; broken session handling.
  • Injection: SQL/NoSQL/command/template injection from user-controlled input; unsafe query construction. An argument array with no shell removes shell injection, not option injection: a lower-trust value that can start with - is still security.injection, and the finding names the flag an attacker could pass. Nor does it protect a value the target program itself interprets: a -c or -e code argument, a .bat or .cmd target on Windows, which re-parses its arguments through cmd.exe, or a URL or path the program then fetches, which is SSRF.
  • Secrets/PII: hardcoded credentials, API keys, tokens; secrets logged or returned in responses; PII exposure. A key shipped to the client is judged by what it can reach, not by the fact that it ships: establish every API and data store it can call (many keys, Google AIza keys among them, work on every API their project enables), whether the rule in front of it limits each caller to that caller's own data (an account anyone can register counts as none), and whether anything caps its cost. A key that can read or write data another caller owns, take an action the server should authorize (send mail or messages, notify users, write shared state, trigger jobs), or spend without a hard cap is a finding wherever it ships; rate it by the anchor its reach meets and cite what it can reach. A hard cap is a spend or quota limit the owner set at a loss they accept; provider default rate limits and budget alerts are not caps. Referrer and app-identity restrictions are headers any non-browser caller can forge.
  • Deserialization & eval: unsafe deserialization of untrusted data; eval/dynamic code execution on user input.
  • Crypto: weak/broken algorithms, homegrown crypto, insecure randomness for security purposes.
  • CSRF / SSRF / open redirect introduced by the change.
  • Feature-gate / secret leaks that should stay gated.

security is a skill published in the GitHub repository tufantunc/review-pro (5 stars, last pushed yesterday), licensed MIT. It adds 63 tokens to every session and 2,248 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
